Using a '68 OHC 6 as the subject, I see rockauto still lists a new flywheel, LUK LFW131...:

LUK LFW131 Specifications:

Flywheel Diameter (IN) 10.969
Flywheel Inner Diameter (IN) 6.406
Number of Teeth 153

As a correct fit for the 4.1L engine, but it also is stated to fit a 5.7L LeMans V8, so, not sure how accurate the rockauto listing is.

It's been a while since I priced out a flywheel resurfacing, but it has to be around $50-$60 these days. However, the RA listing for the above LUK flywheel is $68 or so, which makes things much easier to buy and install a new flywheel...if they fit and function the same as an original GM flywheel.

Looking at OHC 6 flywheels online, as well as the pic Jeff H added in another topic, the LUK and factory flywheel are visibly quite different, with the LUK flywheel appearing much less "full" if that makes sense-- much less material around the outer perimeter/circumference, just inside the ring gear:






Honestly, it doesn't look "right", and using an original and having it resurfaced would be the safe route, but I'm just curious if anyone has used a new flywheel on an OHC 6 and if so, how did it work out?
